How did Stalin respond to this criticism?

In 1948, Stalin was upset with the 'occupational zones' (Soviet east zone - US,UK,French west zone) set up in Berlin. He expected that blockading the city from western supplies would cause the western Allies to give Soviet's control of the city. The U.S refused, and the Berlin Airlift ensued, in which allied bombers flew over 600 tons of food a day into Berlin, the Soviets soon saw the blockade wasn't working, and lifted it, after being publicly humiliated over the total failure of the blockade.

when studying cause and effect, historians usually group the causes into different categories. for example, cultural causes reflect how a society’s literature and art convey the way the society saw itself in relation to the rest of the world. another resource that historians use to understand society is pop culture, which tells them the trends and ideas that are preferred by the common people. when studying cause and effect, it’s important to remember multiple causation, or the idea that an effect could have several causes and vice versa.  

the correct option is “cultural causes” since art and literature are related to the culture of a place. culture is determined by literature, art, music.

the correct option is “pop culture” since it reflects the likes and ideas of common people whereas the rest of the options do not focus on common people.  

the correct option is “multiple causation” since it refers to the idea that events are caused by multiple reasons, not just a single one.
